Muscle Tone Anatomy

Muscle tone also known as muscle tonus or residual muscle tension is an unconscious low level contraction of your muscles while they are at rest. All muscles maintain some amount of muscle tone at all times unless the muscle has been disconnected from the central nervous system due to nerve damage.

Muscle tone provides a slight tension on the muscle to prevent damage to the muscle and joints from sudden movements and also helps to maintain the bodys posture.

Muscle tone is accomplished by a complex interaction between the nervous system and skeletal muscles that results in the activation of a few motor units at a time most likely in a cyclical manner. In this manner muscles never fatigue completely as some motor units can recover while others are active. The muscle tone in his right leg and both arms was grade 3.

Muscle spindles are found in all skeletal muscles. They are more highly concentrated in muscle utilizing fine delicate control and less so in the large antigravity support muscles. Vaccine derived poliovirus thailand 2003 prader willi syndrome pws is a complex genetic disorder that typically causes low muscle tone short stature incomplete sexual development cognitive disabilities problem behaviors and a chronic feeling of hunger.

Muscle tone is usually defined as the amount of contraction in a resting muscle. Essentially muscle tone is what makes your muscles still feel somewhat firm while you are resting and not intentionally tensing them. However he could not move his left leg.

The greatest percentage of spindles are located in the belly of the muscle. Spindles contain two types of intrafusal fibers. In physiology medicine and anatomy muscle tone residual muscle tension or tonus is the continuous and passive partial contraction of the muscles or the muscles resistance to passive stretch during resting state.

A more detailed definition would be a static balanced isometric contraction between agonist and antagonist both internal forces in every muscle in the body for the purpose of maintaining joint integrity and posture.
